I updated my blog to this Frontier Theme two weeks ago. I love it. You did a fantastic job! Thanks! However, I am having one problem with the links. It seems that each page now has an extension on the URL that wasn't there before.

Quick question about permalinks. I am using the Frontier setting and my website has been live for three weeks now. http://www.woodbridge.lioninc.org/
If I change the permalinks from the default to the post name will all of my links to other pages still work or will I have to go in and change them? Also, will changing the permalinks have any other negative affects on immediate usability, should I have changed them in the early stages of the website build?
